Jacob Rees-Mogg

Nothing less than pure Brexit will do for Rees-Mogg. The charismatic backbencher has more of a platform than ever after Moggmania took hold over the summer.

Rees-Mogg has brushed off suggestions he might run for leader while not quite ruling it out, telling ITV’s Piers Morgan, “This is all good silly season stuff, it was fun in August when there wasn’t much news about. A gentleman in Rotherham got Moggmentum tattooed on his chest, which was very kind of him.”

He is not afraid to set out an alternative vision to the government’s — most recently taxes leveraged on property purchases. This young fogey, who has mastered the art of parliamentary procedure, is underestimated at the government’s peril.

For Rees-Mogg, Brexit is all about sovereignty. A whiff of the U.K. remaining under the jurisdiction of the European Court of Justice, and Rees-Mogg’s support for May could ebb away swiftly.
